Describe the three techniques most frequently used for automatic tracking of production parts and materials (Select the three best answers from the choices given below.)

audio-frequency tone generation when exiting work cell

bar code reading with hand-held and fixed station scanners

binary code pattern generation on production pallets

radioactive isotope emission tracing with Geiger counters

radio-frequency tags using electric circuits to transmit a code

vision systems with miniature camera on production pallets

Solution

a. audio-frequency tone generation when exiting work cell

every item is tracked individually on the exit by giving a tone on detecting a item so it gives one tone per item on the exit station

b. bar code reading with hand held and fixed station scanners

the bar code on the item is unique for all items so every item is scanned at the production with accuracy.

f. vision systems with miniature camera on production pallets

vision systems are at different sections of the production, every station is being moitored from start of raw material to the end product at exit station for quality and quantity check.
